[name]

Create a smooth 3d spline curve from a series of points using the [link:https://en.wikipedia.org/wiki/Centripetal_Catmull-Rom_spline Catmull-Rom] algorithm.

Example


//Create a closed wavey loop
var curve = new THREE.CatmullRomCurve3( [
	new THREE.Vector3( -10, 0, 10 ),
	new THREE.Vector3( -5, 5, 5 ),
	new THREE.Vector3( 0, 0, 0 ),
	new THREE.Vector3( 5, -5, 5 ),
	new THREE.Vector3( 10, 0, 10 )
] );

var geometry = new THREE.Geometry();
geometry.vertices = curve.getPoints( 50 );

var material = new THREE.LineBasicMaterial( { color : 0xff0000 } );

// Create the final object to add to the scene
var curveObject = new THREE.Line( geometry, material );

Constructor

[name]( [page:Array points] )

points – An array of [page:Vector3] points

Properties

See the base [page:Curve] class for common properties.

[property:Array points]

The array of array of [page:Vector3] points that define the curve.

[property:Boolean closed]

The curve will loop back onto itself when this is true. False by default

[property:String type]

Possible values are `centripetal` (default), `chordal` and `catmullrom`.

[property:float tension]

When [page:.type] is `catmullrom`, defines catmullrom's tension. Defaults is *0.5*.

Methods

See the base [page:Curve] class for common methods.
